Answer 1

True' Leukonychia

WHITE SPOTS ON NAILS ARE FROM LEUKONYCHIA

COULD BE FROM INJURY TO THE BASE OF YOUR TOE.

This is The most common form of Leukonychia, small white spots on the nails. Picking and biting of the nails are a prominent cause in young children and nail biters. In most cases, when white spots appear on a single or a couple of fingers or toes, the most common cause is injury to the base (matrix) of the nail. When this is the case, white spots disappear after around eight months, which is the amount of time necessary for nails to regrow completely.[7]

True' Leukonychia Could be from ZINC DEFICIENCY OR

BITING NAILS OR PICKING AT THEM ( doesnt apply to you

as its on your toe)

White spots showing up on all or nearly all nails for longer periods of time (months and years) can be due to one of several reasons. One common explanation is zinc deficiency.[8]
